Interphase: Add mushrooms to represent organelles and a ring of pepperoni to make a nuclear membrane. Strips of peppers would represent the DNA inside the nucleus. To model the end of interphase, double the number of mushrooms on the pizza to indicate the copying of the organelles. Double the number of peppers inside the nucleus to represent the replication of DNA.
Prophase: Pair strips of pepper inside the nucleus to show the formation of chromosome pairs. Strips of aluminum foil would represent spindle fibers.
Metaphase: Line up the pair of peppers along the middle of the pizza. Removing the pepperoni would show the breakdown of the nuclear membrane.
Anaphase: Split up the pairs of peppers, and show the spindle fibers, made of aluminum foil, pulling them to either side of the cell.
Telophase: Make two new nuclear membranes around the pepper strips using pepperoni. Separate the pairs of peppers to show the chromosomes unwinding.
Cytokinesis: Cut the pizza across the middle to show the cell dividing into two daughter cells.
This statement means that evolution has happened by getting the genes of the right trait expressed at the right time to help adaptability.
Explanation:
Evolution is a result of natural selection which emphasize on the survival of the fittest. But the occurrence of this trait has been possible with genetic variation. It means that if the genes for the particular feature is not present in the genome how would it occur and adapt to the environment. Thus, evolution promotes the most available option for the adaptation and hence for natural selection.
We can conclude that all features are not adaptable some are the results of genetic drift or mutations.
In case of cheetah, the faster running genes would have been there they got expressed over the period of time for better adaptability.
<h3><u>
Answer:</u></h3>
<u>When scientists report their results from their scientific investigations, scientists should include the content that answers the following questions</u>
- Was our hypothesis correct?
- Do we need to run experiment again,changing a variable?
- If the results did not support the hypothesis then add information about reason why it happened.
<u>Scientists should not include the following </u>
- It should not oppose your results.
- Conclusions should not be in a negative tone.
(B) The isolated hectare plots increase the ability of individuals to disperse from one habitat to another.
<h3>What is a Ecologist?</h3>
In the 1990s, the reintroduction of wolves to Yellowstone National Park garnered widespread media attention and significantly increased the park's biodiversity. Unfortunately, the spread of exotic species like zebra mussels, Kudzu vines, and Burmese pythons in other regions of the United States more than offsets this success for native ecology.
The diverse roles that different species play in their communities make changes to those ecosystems very disruptive. Ecologists can aid us in making better decisions that reduce the effects of our actions on other species and the world by deepening our understanding of how nature functions.

The area is dessert with less than 25 cm of precipitation a year, most of which occurs during the year in the deserted area of the whole world.
<h3>What are the areas that have the less rainfall?</h3>
Dryland forests could be receiving much less than 500 mm rainfall. This kind of woodland is specially located in South-East Asia, Latin America and South Asia. Also, Indian has round 60% of tropical dry land woodland.
Deserts just like the Sahara Desert in Africa acquire as much less as 25 cm rainfall in step with year, and the plants and fauna of the region, therefore, are such that keep water for lengthy durations of time, and do now no longer want a lot water to grow.
